ENGLISH SAFETY PRECAUTIONS This appliance is not intended for use by person (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. WARNING INSTALLATION WARNINGS Be sure to ask a dealer or a store specialized in electric work to install the air conditioner. If the air conditioner is improperly installed by yourself, it can cause some problems such as water leaks, electric shock, fire, and so on. Please request the dealer or a specialized technician to perform the grounding work. If the grounding work is performed improperly, an electric shock can result. Do not connect the ground wire to gas pipes, water pipes, lightning rods or ground wires of telephones. If the air conditioner is improperly grounded, it can cause an electric shock. Be sure that the power supply has dedicated air conditioner circuit at the rated voltage. Otherwise, a breakdown or fire can result. Do not install in locations where the unit will get splashed by water or with high humidity such as bathrooms. This can cause deterioration of the insulation, resulting in an electric shock or fire. Do not install the unit in a place where inflammable gas can leak. A fire can result if inflammable gas accumulates around the unit. CAUTION TO DISCONNECT THE APPLIANCE FROM THE MAIN POWER SUPPLY A switch or circuit breaker that can disconnect all poles must be included in the fixed wiring. Be sure to use an approved circuit breaker or switch. OPERATION WARNINGS Avoid cooling the room too strongly or exposing yourself to cool wind for a long time because it can be detrimental to your health. When you notice something unusual with the air conditioner (such as a burning smell or weak cooling power), immediately turn off the main switch and the circuit breaker from the main power supply to stop the air conditioner, and contact the dealer. If the air conditioner is operated continuously when something is wrong, it can cause machine failure, electric shock, fire, and so on. Never turn the circuit breaker on or off, or operate the buttons when your hands are wet. An electric shock can result. If the air conditioner has poor cooling or heating performance, a refrigerant leak may be the cause. Therefore, please contact the dealer. The refrigerant itself used in this air conditioner is safe. Although the refrigerant normally does not leak, in the event that it does leak, toxic gas can be generated if it comes into contact with a flame such as from a fan heater, oven, or stove burner. Do not stop the air conditioner by setting the circuit breaker to off. To stop operation, press the stop button on the remote control. An electric shock or fire can result. Never try to clean the inside of the air conditioner yourself. Please request the dealer to clean inside the air conditioner. If the cleaning inside the unit is not performed properly, the plastic parts or insulation for the electrical parts can be damaged, resulting in a water leak, electric shock, or fire. If water or a foreign object gets inside the unit, immediately stop operation, and set the circuit breaker to off. Continued usage can result in a fire or electric shock. Please request repair from the dealer where you made the purchase. Never insert fingers or sticks into the air outlet and air inlet to avoid getting injured and damaging the machine because there are fans running at a high speed and a heat exchanger inside both the air inlet and air outlet. 1 EN

8 . MOVEMENT AND REPAIR WARNINGS Do not attempt to move or repair the unit by yourself. Do not disassemble the unit. As there is high voltage inside the unit, you may receive an electric shock. Whenever the air conditioner needs repairs, request repairs from the dealer. If the air conditioner is repaired improperly it can cause an electric shock or fire. Always ask the dealer to move the air conditioner for re-installing it in another place. If it is improperly installed, it can cause electric shock or fire. CAUTION INSTALLATION CAUTIONS Ensure that the condensate drainage is sealed throughout the system to prevent any possible water damage. Securely lay the drain hose for the best draining results. Do not place other electrical products, furniture, or other objects below the unit. Water droplets can fall, resulting in stains or damage. Check that the earth leakage breakers are installed correctly. Improperly installation of the earth leakage breakers can result in an electric shock. For the checking procedure, please contact the dealer who performed the installation, or a specialized installation dealer. OPERATION CAUTIONS Carefully read this manual before starting the air conditioner. The manual includes a lot of important information for daily operation. Do not use this air conditioner for other purposes such as preserving food, precision instruments, art objects, breeding animals, or growing potted plants. Avoid exposing potted plants and animals to wind from the air conditioner because it harms their health and growth. When the air conditioner is operated in close proximity to a combustion device, pay careful attention to ventilation and let fresh air into the room. Poor ventilation can cause an oxygen shortage. Do not place any combustion device in a place where it is directly exposed to wind from the air conditioner. Doing so could cause incomplete combustion. When the air conditioner is used in a closed room, pay careful attention to the ventilation of the room. Poor ventilation can cause an oxygen shortage. When the air conditioner is not to be used for an extended period of time, turn off the main switch or the circuit breaker for added safety. Check the concrete blocks underneath the outdoor unit occasionally. If the base is left damaged or deteriorated, the unit can topple over and could possibly cause an injury. Do not put anything on or step on the indoor unit and outdoor unit. If you do so, it can topple over and cause an injury. To allow the air conditioner to operate at maximum performance, operate within the operating temperature range specified in the instructions. Failure to do so can cause a malfunction, break down, or water to leak from the unit. Prevent any liquid from falling on to the remote controller. If this indoor unit is connected to the multi outdoor unit and the heating is operated on multiple indoor units at the same time, when the outside temperature is low it may not be possible to obtain a sufficient airflow temperature. In locations where this is likely to occur, we recommend using the unit in combination with other heating equipment. Do not wash the unit with water. This could cause an electric shock. Do not touch the inlets or aluminum fins of the unit. An injury could result. Do not run for extended periods at high humidity (80% or higher) such as with a window or door open. Condensation can form on the indoor unit, causing it to drip onto furniture and other objects. If there is a danger of a lightning strike, stop operation and set the circuit breaker to off. If lightning strikes, a breakdown of the unit can occur. Do not place objects around the outdoor unit, and keep it clear of fallen leaves. If fallen leaves and other objects collect around the outdoor unit, small animals can come and get inside the unit and touch its electrical parts. This could cause a breakdown of the unit or a fire.
